[PATCH v2 0/4] migration & CI: Add a CI job for migration compat testing

Posted by Fabiano Rosas 10 months, 3 weeks ago

Here's the second half of adding a migration compatibility test to CI.

We've already added support for running the full set of migration
tests with two QEMU binaries since commit 5050ad2a380
("tests/qtest/migration: Support more than one QEMU binary"), now
what's left is adding it to the CI.

I included patches that solve the problem of testing older QEMUs with
new test code. The old QEMU might lack features, bug fixes, etc. that
the tests expect to be present. After this series we can specify a
minimal QEMU version that a specific test supports.

changes since v1:
 - fixed version comparison to be useful for the development tree
 - s/who/qts/g

CI run: https://gitlab.com/farosas/qemu/-/pipelines/1126977964

v1:
https://lore.kernel.org/r/20231207155809.25673-1-farosas@suse.de

Fabiano Rosas (4):
  tests/qtest: Add a helper to query the QEMU version
  tests/qtest/migration: Add infrastructure to skip tests on older QEMUs
  tests/qtest/migration: Adapt tests to use older QEMUs
  ci: Add a migration compatibility test job
